isisebenziso se-server HDD esikhanyisiwe

I-HDD yamaserver enkqokwana ngumxube ophambene kakhulu ekuvulelweni kwemfanelo modern data center, inikeza amathindlela okubuya futhi ukufaka phela okungasebenzi chuma. Le ndawo yokugcina izinhlelo zokwenza nezindlela zokuxhumana ezinezindlela eziphumelelayo okunikeza amathindlela emasimini esebenza. Le teknoloji ibandakanya i-protocol zohlelo oluphambene oluhlinzekayo ukuthi idatha ingavunyelwe lapho kushintshwa, kanye nezindawo zokuphila kanye nezinqawomthetho eziphambene. Le disku zinikeza amathisi wokukhombisa, avela ukuthi kuyisicaba sokuthola futhi ukuthi isebenza kanjani. I-architecture ikhankanyela imigcindeko lestorage nezindlela, iyekela SAS kanye neSATA, okwenza wayisebenzisa kakhulu kuzindlela ezahlukene. I-HDDs zamaseva enkqokwana zibaluleke kakhulu kuzinto zeRAID, zinikeza amathindlela okushintsha ngokushesha lapho kunezimo zokulahla futhi ukuhloli kusebenza. Zibandakanya amathiselwe ohlelo lokusebenza kanye nendawo yokuhlinzeka kanye nokulungisa iphutha, ukuthi idatha ingavunyelwe lapho kushintshwa. Idizayini ibandakanya amathindlela okuhlukanisa kanye nezinkawomthetho zokugcina okunakekela ukuthi kuthathwa futhi kuthathwe ngokushesha, futhi ukuvikelwa kwekho ukuthi kuthathwe ngendlela engaziwa. Le disku zingaba yisisekelo sokuba kuyiphambene kakhulu kuzindlela zokusebenza kahle, zinikeza amathindlela okusebenza ngaphandle kwekhambi, kuzindlela zokusebenza kwedata centers, amathuluzi wecloud computing, kanye nemilayezo yedatha.

Imithombo ye-HDD yaseveri esikhanyelwe ngezikhathi zonke ibonisa amatholakalelo amaningi ayanekileyo okwenza yena ngumoya wesikhathi esisha kuzo zonke izinhlanhla zaseveri. Isibonelo esikhulu ngokukhulu yindlela yokuthi ubenze ubuke izinhlobo ngaphandle kokulayisha isisitemu, okwenza ukuthiwanele kakhulu ukusebenza kwamavikeli futhi ukuthi kube khona ukusebenza okuphephileyo kwamavikeli. Le nto iyisigaba esikhalelwayo kuzo zonke izinhlanhla ezenziwa ngokuphelele ezibonakalayo kusisitemu. Abasebenzisa bakhona ukwenza ukulungisa, ukuvuselela, noma ukubuya ngaphandle kokuthintana nabasebenzisa noma izinhlobo zokusebenza. Le mithombo inemigomo yokuphepha okuthintana nokulahla kwezinhlobo, okwenza ukuthi kube khona ukuphephile kwezinhlobo zonke izikhathi. Kusibonelo sokwenqaba, izinhlobo esikhanyelwe ngezikhathi zonke zenze ukuthiwanele kakhulu ikhosi yokusebenzisa ngokuthi kuthintana nezimo zokusebenza futhi zithintana nezimpawu zokwenqaba. Zonke le mithombo zenze ukuphephile kwezokuphatha izinhlobo ngokuthi abasebenzisi bakwazi ukwenza ukulungisa kusikhathi esijwayeleweyo sasevikeli noma ukulayishwa kwezinyathelo. Le teknoloji isekela ukuplanisa izinhlobo ngendlela efanele, ukwenzela ukuthi kube khona ukuthuthukiswa kwezinhlobo ngendlela efanele. Le mithombo inemigomo yokuthi ayikho ukudinga kwezinsiza okuthintana nokulungiswa kwezinhlobo futhi zenze ukuthiwanele kakhulu ukuthi kube khona ukuthintana nezimpawu zokwenza ngokulungisa. Imigomo yokuhlela kahle iyekela ukuthi kubone amaphutha okungenzeka kwezinhlobo ngaphambi kokuthi ayanekileyo kusisitemu, ukwenzela ukuthi kube khona ukulungisa ngokulula. Imigomo yokuphakelwa kanye nezinhlobo zokuxhumana zenze ukuthi kube khona ukutholakala kwezinhlobo kuzo zonke izinhlanhla zaseveri, ukwenzela ukuthi kube khona ukutholakala kwezinhlobo kuzo zonke izinhlanhla. Le mithombo kanye nazo izinhlobo zokuphatha amandla, okwenza ukuthi kube khona ukuthuthukiswa kwezokuphatha amandla kuzo zonke izinhlanhla zedatha.

Isicathami Esikhulayo Sokuphepha Idatha

I-HDD yomsebenzisi yekhishwa ngokushesha iyafaka amamekhanismu okulungisa idatha engcwele ukuthi ayikho imiphumela yedatha kusikhathi sokukhishwa kwezinhlayiya. Le teknoloji isebenzisa izinhlobo zokuvula izinsimbi ezithuthukiswe zokugcinwa kwedatha ngokwemthetho wepowe nokuhlela kwezinhlayiya kusikhathi sokukhuphuka nokungenisa izinhlayiya. Isisitemu isebenzisa ifirmware esizithuthukisiwe esiyindlela nekontrola ye-RAID yomsebenzisi ukuthi ikheshene ne-verification yedatha. Izinhlobo eziningi zokukhangela amaphoyinti zihlinza izimo zenhlayiya kusikhathi sokukhisha, ukuvikela ukungcola kwedatha. Teknoloji iyafaka noma ukubeka iphowa ekuxazeni ngokuzenzakalelayo yokuvikela ukungabi nomdla kusikhathi sokwenza uhlelo. Lezi zindleko zokulungisa zisebenza ngokushakele ne-OS yomsebenzisi ukugcina ukulinganisa kwedatha nokuthulwa kwesistimu kuwo wonke umthamo.

Izinhloso zokuthembeka zokusebenza

I-HDD zabhotela yezivikele zokusebenza ngokuphelele kuzo izimo eziphakeme kakhulu. La madive anemoto wezibophezo ezinhlelweyo ngokulandelana nezindlela zokubeka fanye nezinkinobodze ezangaphakathi. Izinhlelo zokuphatha intamo ezinhlelweyo ziyasalela ubude bendawo bokusebenza noma lapho kunezindauzi eziphakeme. La madive afaka phakathi kwezilwanywayo zokulungisa amaphoyinti angacabanga ukuthi akwazi ukulungisa iziphoso datha ngokushesha, okuyisigaba sokugcina datha. I-Mean Time Between Failure (MTBF) ingxenye engaphezulu kuka-1.5 milione i-ilayili, okuqukethwa kweqile kahle kanye nokulinganisa kwamagciwane esetshenziswa. La madive iyasebenzisa imithwisto elijwayelekile embuyiselweni, kanye nemadoda amaningi athola iziphosho ezigcinileyo.

Ukuhlangana kanye nokuphathwa

Ukuhlelwa kwe-HDD yomncedisi oqukethweyo kuyindlela elula yokuhlangana nokuphepha ngaphandle kwe-infrastructure yomncedisi. Iidrivu zinamandla amanqaku alinganisweyo kunye neeminye yezixhobo ezisebenzayo ekuxilweni kwazo zonke iiplatfomi zomncedisi. Iifirmware zokuphepha engcacileyo zenziwa ukugcina isiqhelo sokulinga nendawo, ukuguquguquka kweemeko, kunye nemanyenye amathuba. Iidrivu zixhasa imikhiqizo ye-management eziphambeneyo, ejikelezela ukuthunyelwa okulula kwiindlela zokuphepha. Iindlela zokubonisa ziphawuleza iziphumo, ukunceda abasebenzisi ukwazi ngokukhawuleza imeko yedrivu. Ukuhlelwa ngaphandle kwezixhobo kwenza ukusetyenziswa nokususa kube lula, kubothelela ixesha lokuphila kwaye kube lula ukungena ngemali. Iinkqubo zokuphatha amandla zenziwa ukusebenzisa amandla ngendlela efanelekileyo ngelixa kuzinzile imeko echanekileyo.
